It'S Gone Insane.

To be honest with those fish in that sized tank I would suggest 100% changes daily, I'm thinking that bioload in just 6l of water... 50% is unlikely to be big enough.

It has been explained what is causing the problems.

And the only advice I can give is to re-home them both to a larger container of water (or back to the fish shop). If you are willing then I know for a fact that large shops such as Sainsburys sell plastic storage containers that would work as a perfect temporary tank for your fish.

I had a quick look the other day and I think the 30l storage tubs were...£7 or so.
I think you'd notice a huge change in the fishes behaviour straight away. Also if you could get hold of a cheap power filter or at the very least and air pump and air stone this would really help your loach.

as soon as i sent the last post i thought about a large plastic container. so thanks for including that in the options for the OP. THAT would be the easiest thing to do right away! then get looking for a more suitable, permanent home.
could anyone include a link to cycling. dont know why i dont have one but im sure someone reading this has the link.
best of luck!

To cycle you need a filter, be it and internal power filter, air driven sponge filter or hang on the back filter. (there is also one called an undergravel filter but they're far more hassel than they're worth)

If you keep the fish then you'll be --> Fish in cycling

If you re-home the fish then you can --> Fishless Cycle

Just been having a nosey online...

16.7l storage tub = £3.99 @ Staples
31l storage tub = £3.99 @ Sainsburys

another thought...if the OP gets a bigger container (i say container as it would most likely be the cheapest/easiest option at the moment for this person to get a plastic tub until they find a better tank, definately get an airpump with some extra tubing. and some filter sponge or even floss. you could MAKE your own filter out of these things very very easily. but it would not be possible in the smaller "tank" you have them in. it simply would take up too much room in such a tiny space. would be great for the larger tank on the horizon (hopefully) and doesnt cost all that much to buy the necessities (airpump would be the biggest cost, but a small one would suffice and they are pretty inexpensive. that is if you dont want to spend the extra cost for a commercial filter for a larger tank.
just another thought
